s claims. (o1. 139-92) The object of the invention is to provideimprovements in tape selvage harnesses and especially in the heddle barmountings within the frames and the supports therefor.

Another object is to provide a one-piece tape selvage frame, comprisingupper and lower parallel sections, which are preferably of increasedstiffness, and parallel side sections, connecting the corresponding endportions of said rstmentioned sections, said side sections beingrelatively resilient transversely.

A further object is to providea one-piece frame of this type from a pairof similar, initially separate metallic members, which are riveted,Welded or otherwise secured together in unitary relation.

Still another object is to provide a frame of this character having sidesections provided with aligned apertures, in combination withabbreviated heddle bars also having apertures and extending through theapertures in said frame sections, the metal of a side frame sectionbeing squeezed or otherwise deformed or so deected from its initialcondition or position, as to enter one of the apertures of eachintervening heddle bar, to secure the same in xed relationshiptherewith, While the opposite end portion of each bar extends looselythrough the aperture in the opposite side section, and is normallyprevented from release or escapement therefrom by the inherentresiliency of said side sections, augmented by the longitudinal tensionplaced upon them. However, in order to still further insure against thebars accidental escape, there is provided a transversely arranged pin orthe like, which extends through the bar aperture and engages the outersurface of said adjacent side section.

A lstill further object is to provide the combination of a frame of thisnature, in which the side sections are provided additional aperturesadjacent to their opposite ends, and resilient hails having flattened,hooked end portions normally entering said apertures, and removabletherefrom by expanding said bail by flexing its sides or legs outwardly.

With the objects thus briey stated, the invention comprises furtherdetails of construction and operation, which are hereinafter fullybrought out in the following description, when read in conjunction withthe accompanying drawing in which Fig. 1 is an elevational view of atape selvage frame comprising one embodiment of the invention; Fig. 2 isan enlarged fragmentary section on the line 2-2 of Fig. 1; Fig. 3 isVanenlarged fragmentary section on the line 3 3 of Fig. 1; Fig. 4 is afragmentary view of a portion of said frame distorted so as to releaseheddles from one of the heddle bars, the opposite ends of the entireconstruction being to all intents and purposes duplicates; Fig. 5 is anenlarged fragmentary view showing a modied form of bar-securing meansengaging within a cutaway position of the heddle bar instead ofextending through an actual aperture therein; and Fig. 6 is a section onthe line 6--6 of Fig. 5, the resilient clip being shown in elevation.

Referring to Figs. 1 to 4 of the drawing, it will be understood that theframe per se may comprise a single piece of ribbonlike wire or similarmaterial, but in its preferred embodiment consists of two like similarU-shaped members, which can be economically stamped and formed from twoexactly similar pieces of metal. One of these members comprises a sidesection I connecting two oppositely positioned end sections 2, while theother member is of the same shape and comprises a side section I and endsection 2'. The ends of the two pieces are assembled so that theypreferably overlap, thereby providing a unitary joint formed in anysuitable manner, as by spotwelding at 3, or by piercing the ends toprovide pairs of aligned apertures in which rivets or socalled Bostickstaples can be inserted.

Each of said side sections is provided with slender, elongated apertures4 fairly close to the adjacent end sections, and into opposite pairs ofwhich apertures normally extend the ilattened, inwardly directed, hookterminals 5 of a bail,

which additionally comprises resilient legs 6, connected together attheir outer ends by centrally positioned sections 1, which aresurrounded by orf proved frame and the heddles carried thereby.l

Either or both of said bails are released from the said frame byspreading the legs 6 outwardly in opposite directions, as shown at thetop of Fig. l.

Inwardly from the respective pairs of bail-receiving apertures 4, areadditional pairs of slender, aligned apertures 9 and 9 in the oppositelypositioned side sections I and I. Referring to one of these pairs, ofwhich the other pair is a duplicate, a relatively short heddle bar Ill,having apertures I I and I2 in its end portions, is inserted into theaperture 9, so that its aperture is substantially centrally positionedwith respect to the adjacent portion of the sur-v the side section uponthe opposite sides of its aperture 9 is pinched or squeezed togetherinto the bar aperture ll, thereby loosely but permanently securing saidbar in operative position, in unitary association with said sidesection.

After both of said bars have been secured in this manner, they areinserted through the usual eyesin the end portions of anyiwell-knowntype of heddle I4, after which the opposite free end of each bar isinserted in the aligned aperture in the opposite side frame sectionaperture 9', by first flexing said side section outwardly as shown inFig. 4, which is also the position and arrangement of the respectiveparts when removing and/or substituting a new heddle-for one that hasalready been in use upon said bars. the vfree end of each bar has. beeninserted through the second side frame section until the aperture l2 invthe bar is outside of said section, a-fastening member I5 of anyavailable and suitable form isinserted. through thev bar aperture andbent or otherwise locked in' place, so as to thereby secure said secondside section against becoming. accidentally dislodged from the adja.-cent end portionof. the heddlebar supported by it. By removing saidfasteningv means, the adjacent side irame section can be easily slippedlaterally away from. the respectiver heddle barsV and the heddlesthereon, removed and replaced at will. l

While said. fastening. means isv shown in Figs. l and 3.. as extendingthrough the heddle bar apertures,.in Figs, 5. and-.6 isshown a modifiedform of c said m.eans consisting of any suitable form of expansible,resilient. clip I6`,. having opposit'ely positioned, parallel legs 1.1which may normally restwithin groovesY pressed inA the opposite sides ofsaidl bars. adjacent tosadside frame sections,l or instead may dependrupon spaced, angularly converging, end portions t8l and.

This modified form oflocking means is illustrated in order.toindicate clearly that the invention `is not dependent. in` any way tothe exact` form of. locking means that. may be used'and that, insteadVof apertures,l cut-out portions, grooves, andthe like,

may' be employed equally well for this purpose. r

InI any case, it will be noted that the security of theheddle-barswithin their supporting side frame sections is not dependentupon the locking means, as infac-t little or no pressure or force' isapplied. thereto, since the longitudinalv tension exerted upon` said.Aside sections by the straps. 8' or the. like, through the. interveningballs, is. suiiiclaim and desire to protect by Letters Patent of theUnited States is:
